As all things develop, options increase. Water purification technology is no different. While the methods of water purification are varied, not all are created equal.
Problems Associated with the Earlier Methods
One of the oldest active methods of water purification is distillation. While not very advanced by any means, it set the standard for water purification technology. The process is simple. Water is brought to a boil in a sealed container with a tube leading to another container. Steam condenses in the tube, and drips into the second container. The problem is anything with a boiling point over 100°C is indiscriminately left behind and anything with a boiling point under 100°C is also collected in the second container. Meaning healthy minerals are lost and chemicals are kept.
More efficient methods of water purification are always in demand, especially designs capable of desalination. Reverse osmosis was developed as an answer to this need. Touting the same strengths and weaknesses as distillation, it justified its existence by needing far less maintenance and human interaction than a still, and producing far more water. While obsolete outside of desalination, you will still find people trying to sell this relic of water purification technology.
Developed to remove contaminates without altering mineral quantity, a water purification technology known as the micro-porous membrane was developed, basically a three part sieve. Each part is designed to block smaller infiltrates than the last. Unfortunately, these methods of water purification are unable to deal with chemicals or bacteria.
Ultra-filtration is a highly advanced and extremely customizable water purification technology. Membranes are chemically constructed to block infiltrates of specific sizes. The problem is you want all the infiltrates removed, not just some or one of them. While custom methods of water purification have vast commercial and industrial use, they’re not intended for drinking water.
To remove chemicals, a water purification technology called electrodeionization is available. Unfortunately, that’s all it can do. Any other infiltrates will either be unaffected or reduce the effectiveness of ion exchange based methods of water purification. Meaning water to be electrodeionized needs to first be filtered of all organic infiltrates.
If sieves and membranes aren’t your thing, water can be bombarded with UV radiation. Involving nothing more than a large flat tank and a series of low density mercury lamps, it is a very effective and efficient germicidal technique.
The Answer to These Problems
Despite all the new and interesting methods of water purification, the most effective water purification technology was developed to counter chemical warfare in WWI. Known commonly as activated carbon filtration, it involves simply passing water through a filter constructed of special charcoal. Activated carbon will block pretty much everything harmful, but leave healthy minerals. A small problem is any blocked bacteria will remain in the filter. This problem was corrected by the addition of silver to the design. Referred to as granulated active carbon (GAC), the life of such a filter is greatly extended.
While there are more methods of water purification, here we’ve covered all actual water purification technology. The rest revolve around pseudoscience and false claims.

Water purification technology continues to advance, particularly in the area of in-home or point-of-use methods of water purification. Some very old systems are still being used today. Let’s start with them.
Distillation has been around since ancient times. It was not developed as water purification technology, but as a method of creating alcoholic beverages. It has several disadvantages. The boiling process uses large amounts of energy and also results in the removal of essential trace minerals from the treated water.
Reverse osmosis is sometimes advertised as advanced water purification technology. But, that’s just marketing. Systems have been around for over fifty years and were originally designed for use in large scale treatment plants rather than in the home.
Reverse osmosis uses a membrane to act as a filter. The only substances that are removed are minerals and other contaminants that are heavier than water. It requires electricity for operation, so the cost of use is higher than other methods of water purification.
It is not truly a purifier, because bacterial contaminants are not removed. There is no disinfection with this method. It may be used as one step in a complete process, but in and of itself, it cannot make anything safe to drink.
Chlorination was a leap forward in water purification technology. When it was introduced, waterborne illnesses were rampant in this country. Today, we rarely see an outbreak, but researchers and scientists have warned that chemical disinfection methods of water purification are actually health hazards, themselves. So, if you live in an area where they are used, you need a point of use filter to remove the chemicals before consumption.
Disinfection through the use of UV lights is a relatively new water purification technology. It is cost effective, according to facilities that use it. It is one of the less commonly used methods of water purification because of the expense of installation and because of concerns that chlorine or other chemicals would still be needed to protect the water as it is stored in the tanks or travels down the tubes.
Carbon filtration, multi-media blocks and ion exchange have been responsible for advances in point-of-use water purification technology. They require no additional electricity. They are easily installed, easy to maintain and easy to use. They are affordable and still they remove many contaminants that more expensive methods of water purification cannot.
There are many other methods of water purification in use around the world. Everyone needs clean healthy water for drinking. In poverty stricken countries, waterborne diseases are still a major cause of illness and death, particularly among children.
Many diseases are transmitted through contaminated water-sources. Bird flu, Legionnaires disease, cholera, dysentery, typhus and others are problems all around the world, despite advances in water purification technology.

You won’t be surprised to find out that there a number of water purification technology choices in the marketplace today. Each of these choices uses one or more methods of water purification to produce higher quality drinking water. The challenge to you is understanding which one best meets your needs.
Three kinds of harmful substances in drinking water
The goal of water purification technology is to take out the bad stuff and leave the best quality drinking water behind. Good methods needs to be able to remove any undesirable chemicals, from chlorine to herbicides to inorganic chemicals. In short, most industrial and agricultural chemicals need to be removed.
The body works best with water that is alkaline in nature, and high in mineral content. This helps the body reduce production of free radicals, which are cancer causing agents. Minerals are essential to good health by nurturing the growth of muscles, bones and organs.
Many water supplies also have living organisms called cysts which can be harmful to the body. Due to widespread use of chlorine in municipal water treatment, cysts such as giardia and cryptosporidium have become chlorine resistant and often reach home water supplies.
Three ways to remove these harmful substances
The first technology to meet these needs is mechanical filtration. Today’s technology allows contruction of mechanical filters at the sub micron level. These level of filtration will eliminate both particles as well as cysts like giardia. This technology will also remove a large part of the chlorine found in drinking water today.
The second technology to meet these needs is adsorption. This process focuses on the removal of volatile organic chemicals (VOCs), like herbicides, pesticides and industrial solvents. With these chemicals removed, the health of the water increases considerably!
The third technology to meet these needs is ion exchange. This process removes toxic metals by exchanging the metal ions for other mineral ions that are more beneficial to the body. This improves the mineral content of the water, which enhances the body’s ability to resist disease.
The wrap up on pure water
In conclusion, these three elements of water purification technology represent the best elements of water purification technology. The methods of water purification described here will eliminate the majority of undesired chemicals and organisms, while leaving healthful minerals. As you research the best water filter systems on the market, you would do well to find a system that will use all three of these methods!

Water purification technology has advanced tremendously in the past few years, particularly in the area of home filtration systems. Here’s a brief look at some of the different methods of water purification available today.
Distillation is very old water purification technology, but it is still commonly used. It was first developed, not as one of the methods of water purification, but to create alcohol. In archaeological excavations from Pakistan to South Asia, alcohol distillers have been found. A simple explanation of the process follows.
Liquid is brought to a boil and it vaporizes. The vapor travels through a tube, where it enters another chamber, cools down and once again becomes a liquid. Anything that has a higher boiling point than the liquid or cannot be vaporized in the steam remains in the first pot.
This is one of the methods of water purification that leaves the minerals behind and causes an acid pH. It has been learned that for drinking purposes, de-mineralization and acid pH levels are not healthy.
Advancements in water purification technology have aimed at removing chemical and biological contaminants, without destroying the natural mineral content and pH level.
Reverse osmosis is often touted as the latest in water purification technology, when in fact it has been around for at least 50 years. It was developed for use in industries and large scale treatment facilities. In the 1970s, it became popularized as one of the healthiest methods of water purification for the home.
It was truly a boon to water purification technology, since it can be used to remove salt. In coastal areas and island communities, this is an important and desirable feature. Basically, it works by pressurizing and forcing liquids through a porous membrane. The size of the pores determines what is removed and what travels through.
RO is another of the methods of water purification that de-mineralizes, so not the healthiest for drinking. There are several other disadvantages to the system. It creates wastewater that cannot be used for drinking or other purposes. It operates slowly and requires electrical energy.
Chemical contaminants, such as we face today are not removed. And, additional steps are required to remove bacteria and bacterial cysts. For home purifiers, water purification technology has advanced beyond this method.
In most of our homes, the liquid that flows from our kitchen taps has been through a number of methods of water purification. Treatment facilities vary, but depending on where you live, the methods of water purification used by major facilities include RO, membrane and ultra-filtration, flocculation, UV radiation and, of course, chemical disinfection.
The use of chemicals to kill bacteria and disinfect was, at the turn of the century, a major leap forward in water purification technology.
Before its introduction, there were numerous outbreaks of cholera, typhoid and other diseases relating to bacterial contamination. It appears that what was good for our society in general was bad for the health of the individual.
One of the chemicals most commonly used for disinfection is chlorine. When it is used at the treatment facility, other chemical by-products (THMs) are released. Both, THMs and chlorine, as well as their gases and vapors, have been linked to cancer and a variety of other health problems.
New advancements in water purification technology for the home are aimed at removing those threats. One of the best methods of water purification for this purpose is carbon filtration.
Chemicals and other contaminants stick to the filter, making the output safer to drink. This method also removes odor and improves taste. Most of the newest home purifiers make use of this technology.
This was a brief overview of water purification technology. It would be impossible in an article of this length to cover the subject in its entirety, but hopefully, you are now a little more informed.
